Moves the #666 ask→operator inline-answer wiring rationale from
app.js into a new docs/web-ui.md::Per-agent page sub-paragraph
**Ask → operator inline-answer binding**. Substantial block —
the slot-registry / reconcileAskBinds / buildAnswerForm trio has
real design rationale (async question id, text-match pairing,
resolved-vs-cancelled-vs-expired neutrality, defensive prune,
no-regression-fallback to side-panel answer) that belongs in
docs, not three JSDoc blocks scattered through app.js.
Moved to docs (~30 lines of substantive prose):
- pendingAskBinds slot-registry rationale
- reconcileAskBinds matching algorithm (text-match, first-unbound
to first-unclaimed pairing stability)
- defensive prune for disconnected slots
- [resolved] vs ✓ rationale (answered / cancelled / TTL-expired
ambiguity — neutral label)
- fallback to side-panel answer when slot stays unbound
Collapsed in app.js: 3 JSDoc blocks + inline comments → ~10-line
total pointer. Drops #666 ×3, #559, #668 cookies en passant
(substance now lives in docs).
app.js: 24 → 19 refs in this commit; 27 → 19 across batch 1
(30% reduction so far). Net ~57 lines of substantive prose
migrated from app.js to docs/web-ui.md across both commits in
this PR.
